  • Patent number: 7079082
    Abstract: An improved continuous transverse stub (CTS) antenna has coplanar waveguide (CPW) feed elements spaced apart aligned in parallel and mounted perpendicular to a planar substrate base made of a low dielectric material. A continuous transverse stub extends perpendicularly through a clearance gap in the CPW feed elements on the ground plane of the substrate base. The antenna is fed with a simple coplanar waveguide transmission line formed by the parallel CPW elements. The antenna employs the coplanar waveguide with CTS technology, preferably in a planar microstrip configuration, to produce a broadside radiation pattern with a maximum in the +z direction, perpendicular to the plane of the antenna. The CPW-CTS antenna offers the advantages of a broadside radiation pattern, low input impedance, high radiation efficiency, low fabrication cost, use of simple coaxial or microstrip transmission line feed, and simple integration with microstrip circuitry in a transceiver front-end.

  • Patent number: 7006039
    Abstract: A high-directivity transponder system uses a dual system of a retrodirective array transmitting a data signal peak toward an interrogator source, and a self-null-steering array transmitting a null toward the interrogator source and a jamming signal elsewhere, resulting in high S/N reception at the interrogator source and avoidance of interception. Integrating modulators would allow each array to transmit different data while the spectra of the transmitted signals are identical, thus disabling interception. The system enables secure point-to-point communications and can be used for short-distance wireless data transmission systems such as wireless LAN and RFID servers. As another aspect, self-steering signal transmission is employed for randomly oriented satellites using circularly polarized, two-dimensional retrodirective arrays. Quadruple subharmonic mixing is used as an effective means of achieving phase conjugation when a high-frequency LO is not feasible or inapplicable.

  • Publication number: 20050193320
    Abstract: Various modifications to conventional information coding schemes that result in an improvement in one or more performance measures for a given coding scheme. Some examples are directed to improved decoding techniques for linear block codes, such as low-density parity-check (LDPC) codes. In one example, modifications to a conventional belief-propagation (BP) decoding algorithm for LDPC codes significantly improve the performance of the decoding algorithm so as to more closely approximate that of the theoretically optimal maximum-likelihood (ML) decoding scheme. BP decoder performance generally is improved for lower code block lengths, and significant error floor reduction or elimination may be achieved for higher code block lengths. In one aspect, significantly improved performance of a modified BP algorithm is achieved while at the same time essentially maintaining the benefits of relative computational simplicity and execution speed of a conventional BP algorithm as compared to an ML decoding scheme.

  • Patent number: 6878699
    Abstract: In accordance with the present invention, there have been identified extracts from a tropical plant that initiate paclitaxel-like microtubule bundling. Bioassay-directed purification yields the steroid taccalonolide A. Taccalonolide, like paclitaxel, initiates the formation of abnormal interphaes and mitotic microtubules. Cells treated with taccalonolide exhibit thick bundles of microtubules that appear to nucleate independent of the microtubule organizing center. Abnormal mitotic spindles consisting of multi-polar spindles are initiated by taccalonolide and resemble abnormal mitotic spindles found in the presence of paclitaxel. Like paclitaxel, taccalonolide causes the breakdown of the nucleus into micronuclei. Taccalonolide causes G2/M arrest, Bc1-2 phosphorylation and initiates an apoptotic cascade that includes the activation of caspase 3. Taccalonolide is an effective inhibitor of proliferation against both SK-OV-3 and MDA-MB-435 cell with IC50 values of 2.3 ?M and 2.1 ?M respectively.
